Documents and shall not be extended without written consent of OWNER and ENGINEER. 10.2. VISITS TO THE SITE
ENGINEER will make visits to the site at intervals appropriate to the various stages of construction to observe the progress and quality of the executed Work and to determine, in general, if the Work is proceeding in accordance
with the Contract Documents. ENGINEER will not be required to make exhaustive or continuous on-site
inspections to check the quality or quantity of the Work. ENGINEER's efforts will be directed toward providing for OWNER's greater degree of confidence that the completed Work will conform to the Contract Documents. On the basis of such visits and on-site observations as an experienced and qualified design professional, ENGINEER will
keep OWNER informed of the progress of the Work and will endeavor to guard OWNER against defects and deficiencies in the Work.
10.3. PROJECT REPRESENTATION If OWNER and ENGINEER agree, ENGINEER will furnish a Resident Project Representative to assist ENGINEER
in observing the performance of the Work. The duties, responsibilities and limitations of authority of any such
Resident Project Representative and assistants will be as provided in EXHIBIT B, A LISTING OF THE DUTIES,
RESPONSIBILITIES AND LIMITATIONS OF AUTHORITY OF THE RESIDENT PROJECT
REPRESENTATIVE. 10.4. CLARIFICATIONS AND INTERPRETATIONS
ENGINEER will issue with reasonable promptness such written clarifications or interpretations of the requirements
of the Contract Documents (in the form of Drawings or otherwise) as ENGINEER may determine necessary, which shall be consistent with or reasonably inferable from the overall intent of the Contract Documents. If CONTRACTOR believes that a written clarification or interpretation justifies an increase in the Contract Price or an extension of the Contract Time and the parties are unable to agree to the amount or extent thereof, CONTRACTOR
may make a claim therefor as provided in the General Provisions of the construction Contract Document.
10.5. AUTHORIZED VARIATIONS IN WORK
ENGINEER may authorize minor variations in the Work from the requirements of the Contract Documents which do not involve an adjustment in the Contract Price or the Contract Time and are consistent with the overall intent of
the Contract Documents. These may be accomplished by a Field Order and will be binding on OWNER, and also on CONTRACTOR who shall perform the Work involved promptly. If CONTRACTOR believes that a Field Order justifies an increase in the Contract Price or an extension of the Contract Time and the parties are unable to agree as

10.9.1. ENGINEER will be the initial interpreter of the requirements of the Contract Documents and judge of the acceptability of the Work thereunder. Claims, disputes and other matters relating to the acceptability of the Work or the
interpretation of the requirements of the Contract Documents pertaining to the performance and furnishing of the Work and claims under The General Conditions of the Construction Contract in respect of changes in the Contract Price or Contract Time will be referred initially to ENGINEER in writing with a request for a formal decision in accordance with this paragraph, which ENGINEER will render in writing within a reasonable time. Written notice of each such claim, dispute and other matter shall be promptly reported and copied to the OWNER.
10.9.2. When functioning as interpreter under paragraphs 10.8 and 10.9.1, ENGINEER will not show partiality to OWNER or CONTRACTOR and will not be liable in connection with any interpretation or decision rendered in good faith
in such capacity. The rendering of a decision by ENGINEER pursuant to paragraphs 10.8 and 10.9.1 with respect to any such claim, dispute or other matter will be a condition precedent to any exercise by OWNER or CONTRACTOR of such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any

INTRODUCTION
The Story Mill landfill operated from the 1970s through approximately 2008 with both an unlined and lined cell used for the disposal of municipal refuse. The unlined cell was closed in the 1995 and the lined cell was closed in 2010. Investigations conducted by the City during 2013 and
2014 identified the presence of volatile organic compounds (VOCs) in soil gas both on the landfill property and in the adjacent Phase 3 of Bridger Creek Estates neighborhood. Sub-slab depressurization systems were installed in most of the homes in the Phase 3 neighborhood to
break the possible pathway of VOCs in soil gas migrating from the landfill property toward the homes. Remediation of the source of the VOCs and/or establishing a barrier to prevent their migration off the landfill property was identified as the next step in the project. This Task Order
is directed at developing and implementing a remediation system to meet that objective.
SCOPE OF WORK
This scope of work covers the overall Corrective Measures Assessment process for remediation of off-site migration of VOCs from the former Story Mill landfill site. It provides a detailed outline
of preliminary data collection and pilot testing tasks to be conducted and a more general outline
of the overall CMA and remediation system design process. As the preliminary tasks are completed a more refined scope of work will be prepared with associated costs to complete the
CMA process. TASK 100 PREPARE UPDATED SITE CONCEPTUAL MODEL
Objectives:
• Integrate new data into existing conceptual model and develop overall understanding of
how and where VOCs migrate off of the landfill property.
• Estimate the mass of VOCs being transported off of the landfill property in groundwater
and soil gas.
• Identify the depth and location of preferential pathways for VOC migration in soil gas.
• Identify if there are seasonal changes in VOC transport.
The existing conceptual site model developed by Tetra Tech, presents a simplified description
of our understanding of how VOCs are migrating from the landfill to soil gas beneath the Bridger Creek Subdivision. The traditional vapor intrusion model entails contaminated groundwater
migrating away from a source with VOCs volatilizing from groundwater and moving up through
the vadose zone into buildings at the surface. The presence of 38 VOCs in soil gas at the landfill boundary, but only 5 VOCs above analytical method detection limits in offsite groundwater,
87
Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 2 of 9
indicates that groundwater plays a limited role in off-site VOC migration. Migration of VOCs in the gas phase directly from the landfill is believed to be the primary VOC transport mechanism.
This task is directed at filling data gaps identified by DEQ and Tetra Tech. Data gaps include
selected geographic areas lacking groundwater data and soil gas data at depth along the south
property boundary. Data generated by the ongoing groundwater investigation will be used to modify this conceptual model. This will ultimately drive the focus of the CMA process and
whether it only targets the capture and removal of VOCs in soil gas or also targets VOCs in
groundwater. The geographic extent of the model also needs to be revaluated. The existing conceptual model is based on the assumption that the primary flow path is to the southwest in
soils beneath the unlined cell and Bridger Creek III subdivision. The potential for soil gas migration to the south or east of the landfill also needs to be considered in the Conceptual Model to fully describe the migration of VOCs, which will then allow the City to fully evaluate the
problem.
Subtask 110 Additional Data Collection
Existing data provides considerable insights into understanding the distribution and migration of VOCs from the landfill property. However, several additional data collection efforts are proposed
to fill data gaps and support a more detailed understanding of the site. Field work for this task will follow methods identified in the Sampling and Analysis Plan for the ongoing off-site work.
They include the four tasks described below.
Additional Soil Gas Probes along South Boundary
Soil gas probes will be installed at three locations along the south boundary of the landfill
property. They will be installed with a hollow-stem auger drill rig and split spoon soil samples will be collected at periodic intervals to allow geologic logs to be constructed. These probes will be
paired with BSV 9 and BSV 10 and a new location between BSV 10 and BLG-10 to provide data
from greater depths. BSV 9 and 10 are 22 and 30 feet (ft.) deep, respectively and the new probes will extend to near the groundwater surface, hence they will terminate between 55 and
65 ft. below ground surface (BGS). Two perforated probes will be installed in each boring at
depths to be selected based upon observed geologic materials, however, they will likely be set between 40 and 65 ft. BGS. These probes are directed at investigating the occurrence of
deeper soil gas pathways for the migration of VOCs. Gravels encountered during the recent drilling of MW 17 and MW 20 indicate well indurated silts to approximately 60 ft. BGS followed by a deeper zone of gravels and sands, which may be a transport path for VOCs.
Air sampling will be conducted for TO-15 and Fixed Gases (ASTM-1946-D for methane, oxygen, carbon dioxide and nitrogen) analyses from all existing BSV and BLG probes as well as the
unsaturated zone of several groundwater monitoring wells. A total of 27 samples will be collected, including several quality control samples. Probe pressure and barometric pressure
measurements will also be collected prior to air sample collection.
Evaluation of LFG potential and potential migration of LFG from Lined Closed Cell
Review of existing data does not indicate that the lined closed landfill cell is a source of off-site VOCs, however, a few additional data points would help confirm that case. It is necessary since
the western extent of any remediation system constructed to intercept migration from the
88
Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 3 of 9
unlined cell would need to be established based on confirmed observations. The following tasks are proposed:
• Examine as-builts of waste cell design and extent of liner(s) to evaluate potential for
subsurface escape and off-site migration of LFG and to understand the nature of the cover. Evaluate leachate capture and disposal features and potential to collect
samples/record volume of leachate production.
• Drill into the Lined Closed Cell and complete an LFG well to sample and evaluate the
gas relative to soil gas observed elsewhere on the property. An air sample will be collected for TO-15 and Fixed Gas analysis as well as field measurements of pressure in
well and barometric pressure.
• Evaluate results of LFG system optimization work (under separate task below) and first
two bullets of this task to evaluate whether additional soil gas probes are warranted around the perimeter of the Lined Closed Cell. This would likely entail probes to the west
of BSV 12 and perhaps on the west side of the lined closed cell. The need for these
probes and their location will be determined as part of this task.
Update Survey Current location and elevation data for landfill gas extraction wells, methane monitoring wells,
soil gas probes and other features at the landfill (some roads, pipelines etc.) are approximated
or based on GPS data, others are established by survey. A survey will be conducted by Great West Engineering to establish locations and elevations for all the monitoring stations and other
relevant features. Topographic contours across the Phase III and Phase II neighborhoods will also be generated and tied to the Landfill property contours. The landfill topography is currently based on a local datum and is not tied to State Plane coordinates.
Subtask 120 Conceptual Model Report A conceptual model report will be compiled that presents data in a variety of formats to help
form the revised conceptual model. This will include developing new groundwater, soil gas probe and sub-slab iso-concentration maps of selected VOCs, geologic sections or fence diagrams using geologic well logs, and groundwater potentiometric surface maps. We do not
see value in a numerical groundwater or soil gas flux model at this stage of the project. However, if groundwater is identified as a significant transport mechanism for VOCs from the
landfill then numerical modeling may be warranted to properly evaluate groundwater treatment
alternatives in the CMA process.
An analysis of groundwater concentrations of VOCs will be conducted to evaluate their potential
contribution to VOCs in soil gas. Various representations of data will be used to create a simplified model of subsurface conditions that will describe the relationship between VOCs in
groundwater and soil gas and the primary mechanisms by which VOCs migrate from the landfill
to the soil gas beneath homes in the Bridger Creek neighborhood. This will likely entail a generalized stratigraphy of the area and an approximation of the mass of VOCs moved through
groundwater versus soil gas mechanisms. The extent of both groundwater and soil gas
migration of VOCs will also be identified, with particular focus on the Bridger Creek Phase III neighborhood and adjacent lands to the south and east. Existing soil gas data will be evaluated
during different seasons of the year to evaluate whether there is variability in the concentrations or migration pathways throughout the year.
89
Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 4 of 9
TASK 200 CONDUCT SOIL VAPOR EXTRACTION WELL RADIUS OF INFLUENCE TEST
Based upon analysis of geologic logs (including those from recently completed wells), soil gas
probe and methane well completion intervals and VOCs in soil gas data from existing data sets and new data collected by Task 100, we will identify specific depth and locations that warrant soil vapor extraction testing. Existing gas and methane probes have focused on the top 20 to 30
ft. of soils. Analysis of boring logs from the recently installed monitoring wells near the southeast corner of the landfill indicates there may be migration pathways below the existing 30 ft. deep probes. These intervals will most likely be along the south boundary of the landfill. This
extraction well test will focus on evaluating the volume and concentration of VOCs migrating at different depths along the south boundary, the rate at which they can be extracted and the extraction well spacing needed to inhibit their off-site migration.
We propose to install two, 4-inch diameter vapor extraction wells along the south boundary of
the landfill. The location of these wells will be selected based upon evaluation of the results
from Task 100. The extraction wells will be designed to provide an extraction point at the same elevation as the preferential pathways identified by Task 100. They will likely be screened from
near surface to a maximum depth of 40 to 70 ft. BGS. The extraction wells will be located
approximately 80 ft. apart and centered over an existing BSV probe (i.e., 40 ft. from BSV probe to each extraction well). Vacuum measurements from the deeper BSV probes will allow a more
complete assessment of potential deeper soil gas migration pathways. Pilot testing will entail installing regenerative blowers on the extraction wells and pulling air
through the casing from the subsurface for a period of one month. The volume of air flow from the blower will be measured along with vacuum levels in nearby gas probes and wells on a daily
basis initially then at least weekly for the duration of the test. Air samples will be collected from
the extraction point three times a week for field analysis of total VOCs and methane by Flame ionization detector. At the start and conclusion of the pilot test, air samples will be collected from the extraction wells and analyzed for TO -15 and Fixed Gasses to evaluate changes in soil
gas chemistry.
The data will be analyzed to estimate the radius of influence created at each depth interval and
any indications of interconnectivity between depth intervals. If there is no vacuum created in a probe screened in an identified preferential pathway during the test, then a closer extraction well
spacing may be warranted. If necessary, another extraction well will be installed halfway
between one of the existing extraction wells and the BSV probe (i.e., a spacing of 20 ft.). Another pilot test will be conducted to confirm that the radius of influence is at least 20 ft. We
have not included costs for a third extraction well and a second pilot test since we don’t anticipate it will be necessary. A modification will be submitted if it becomes necessary.
Analysis of this data will support establishing the number, depth and spacing of extraction wells for a soil vapor extraction remediation system. The two extraction wells proposed for this pilot
test will be constructed such that they can be integrated into the ultimate full scale soil vapor
extraction system.

TASK 300 OPTIMIZE EXISTING LANDFILL GAS EXTRACTION SYSTEM
The existing landfill gas extraction system has been designed and maintained with two primary objectives: prevent migration of methane off of the landfill property and reduce the concentration
of VOCs in groundwater downgradient from the unlined cell. Both of these objectives are being
met, however, it may also be beneficial to increase the collection of landfill gasses from the unlined cell as a source control measure to limit offsite migration of VOCs in soil gas. This could
be the primary remediation approach used for the site or as a joint effort with a soil vapor
extraction system.
Tetra Tech proposes to conduct baseline monitoring of all LFG extraction wells (air flow, vacuum, fixed gases concentrations) to determine status of waste LFG production and any trends. This data can then be used to conduct some immediate system optimization (i.e.
increasing the capture of LFG). A ‘surface emissions sweep’ is also proposed to assess if there
are areas where methane and VOC’s are escaping through the cell cover as an evaluation of the collection system and cap effectiveness. This field work will entail collecting gas
measurements near the surface of the unlined cell on a grid system over the entire landfill cover. It is best conducted during late summer.
The data collected by this task will be analyzed relative to evaluating whether additional LFG extraction wells or increasing extraction flows would result in increased source control and
reduction of offsite migration of LFG. This analysis would include evaluating whether increased
extraction flow would maintain generation of LFG. Past evaluations of the LFG extraction system have been qualitative and directed at what extractive flow rate should occur to maintain
LFG generation and ensure methane does not exceed standards at the property boundary. This
will be a more quantitative evaluation directed at improving system operation, cover improvements or other measures.
If increased LFG flow is recommended, then an evaluation will be conducted to determine whether it will be necessary to add propane or natural gas to the flare to maintain operation. It
is assumed, based on past observations, that higher LFG system flows would create lower
methane content in LFG.
The flare system is 17 years old and has not had an upgrade or significant replacements, hence an evaluation will be conducted to identify whether improved combustion of LFG or more continuous operation of the flare could be achieved with equipment updates. Operational
improvements may include having a certified LFG technician inspect/replace/tune components, and changing out the flare tip for one specified for lower or higher air flow and lower or higher
methane levels. Gages and filters should also be inspected and replaced if necessary.
TASK 400 PREPARE CORRECTIVE MEASURES ASSESSMENT REPORT
The corrective measures assessment (CMA) process can be summarized into the following primary components:
• Definition of the Problem
• Identification of Remedial Technologies
• Development and Analysis of Alternatives
• Selection of Remedy
91
Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 6 of 9
DEQ rules (ARM 17.50.1307 through 1310) identify specific information that must be compiled and considered for each component of a CMA report and a formal process to be followed in the
development and selection of a final remedy. Details to be included in each component of the CMA process are discussed below.
Subtask 410 Pilot Study In order to expedite the installation of a remediation system that at least significantly reduces if
not contains the migration of VOCs from the landfill property, we propose meeting with DEQ to
discuss a “pilot test” approach. This process entails making an assessment of the problem after the conceptual model is revised and designing and implementing a proven technology that
can be reasonably expected to intercept a large portion of the VOCs migrating from the property, thereby initiating the decline of VOCs in soil gas in the neighborhood in 2014. This would likely entail an SVE system along the south boundary of the landfill. An initial DEQ
meeting has been conducted to discuss the overall CMA process and to discuss how to
expedite the installation of at least a partial remediation system in 2014.
DEQ approval is required for any additions or alterations within the landfill permit boundary, hence, a pilot study approach would need to be presented to DEQ as a means of providing site specific data on the effectiveness and spacing of SVE technology. We have contacted DEQ in
an effort to set up an initial meeting to discuss the overall CMA project and our approach towards implementing a pilot test measure as soon as reasonably possible. This approach
would still require the full CMA process to be followed on a parallel track which would result in a
final CMA to be completed in late 2014 with full system construction in 2015. The final design might entail increasing the number or coverage of SVE wells installed as part of a pilot study, or
it might add additional technology to the system.
Subtask 420 Definition of the Problem
This portion of the CMA lays the groundwork for understanding the site and the problem, which at this point is defined as the migration of VOCs from the landfill into the adjoining Bridger Creek
Phase III neighborhood. A discussion of the contaminant sources, and transport and fate of
contaminants of concern (COCs) will also be warranted. The conceptual model will be a significant part of this section since it will provide the most current understanding of how VOCs
are migrating from the landfill into soil gas beneath the adjacent neighborhood. This process will utilize existing data from methane, soil probe, indoor air and groundwater
monitoring points, as well as the results from the upcoming groundwater investigation to define the problem, its source(s) and migration pathways. A discussion of fate and risk to human health and environment will be compiled preferably using the results of the ongoing Risk
Assessment currently being compiled for the City. If not, general risk numbers like the Regional Screening Level, Minimal Risk Level or Maximum Contaminant Level will be used.
Subtask 430 Identification and Screening of Remedial Alternatives
This component of the CMA process will use the understanding of the problem developed by
the process defined above to identify technologies that are known to be effective at addressing the defined problem. This will primarily rely on the expertise and experience of key staff, who
have been involved in the design and implementation of hundreds of remedial systems at sites
92
Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 7 of 9
across the country. In addition, DEQ and potentially the public may also identify technologies to be considered for the site.
Subtask 440 Development and Description of Remedial Alternatives
Once applicable technologies are selected, they will be developed into alternatives that address the problem. In some cases, one or more technologies may be combined into a single
alternative (e.g., SVE along property line and enhanced landfill gas extraction from within waste
cell) to best achieve the project objectives. It is anticipated that perimeter active SVE and enhancements to the existing landfill gas extraction system will be given consideration,
however, passive vent trenches and vertical containment barriers may also have merit. If groundwater transport of VOCs is identified as a significant off-site transport mechanism, then air sparging, in-situ biodegradation, pump and treat, and other groundwater treatment
technologies will also be considered.
Subtask 450 Detailed Analysis of Remedial Alternatives
The CMA process stipulates a detailed analysis of remedial alternatives be conducted using DEQ’s established criteria, which include the following:
• Ability to Meet Project Objectives
• Effectiveness
• Time Required to Begin and Complete Remedy
• Institutional Requirements
• Practical Capability of Owner/Operator
• Degree of Community Concerns
• Cost
Subtask 460 Comparative Analysis of Alternatives and Selection of Remedy
Each of the alternatives will be discussed relative to each other for each of the seven criteria listed above. Whether each alternative achieves or fails to meet the requirements for each
criterion will be discussed. This is an interim step toward conducting a numerical ranking of
each alternative relative to each criterion in the subsequent Alternative Selection process. Each alternative will be scored relative to each criteria and a total score will be compiled. Scores
will be selected based upon qualitative analysis for some criteria (e.g., practical capability and
degree of community concerns) and quantitative analysis for others (e.g., time required and cost). The basis for each scoring will be provided.
The final selection may entail choosing one alternative or a combination of alternatives, if it is determined to be necessary to meet the project objectives. The selected remedy will be
identified in the draft CMA report, which will be submitted to DEQ for review. DEQ will subsequently schedule a public meeting, at which time the CMA process will be discussed and the selected alternative identified. DEQ will receive public comments on the Draft CMA and
provide comments to the City for preparation of a final CMA and their preference for the preferred remedy.

Corrective Measures Assessment Task Order Bozeman Landfill Remediation April 24, 2014 Page 8 of 9
Alternatives Likely to be Considered by the CMA It is anticipated that the alternatives DEQ will require to be considered will include, but not be
limited to, the following:
• No Action (i.e., Maintenance of existing home mitigation systems and continuation of
overall site monitoring program)
• Removal of all refuse in unlined cell
• Soil vapor extraction along landfill property boundary
• Groundwater treatment (depending on results of modified Conceptual Model)
• Enhancement to existing LFG extraction system
TASK 500 CORRECTIVE ACTION PLAN DESIGN AND CONSTRUCTION OVERSIGHT PROCESS
Once the CMA process is completed and approved, we anticipate that the project will move into the implementation phase. In general, this phase will consist of detailed design of the selected
action plan, selection of a construction contractor, construction and engineering oversight of the
construction contractor.
PROJECT MANAGEMENT AND REPORTING
Tetra Tech’s management team includes Larry Cawlfield, PE as Project Manager; Kirk Miller as
Program Manager and liaison to ongoing off-site soil gas investigation and home mitigation activities as well as the Conceptual Model, and Mark Pearson as the Assistant Project Manager.

Mr. Rick Hixson, P.E. The City of Bozeman PO Box 1230 Bozeman, Montana 59711-1230
Subject: Estimated Costs for Story Mill Landfill Remediation
Dear Rick:
Previously, we sent you a proposed Scope of Work to conduct tasks related to the Corrective Measures Assessment
for the Story Mill Landfill. Based on the discussions we had with the Department of Environmental Quality last week, we have modified the Scope of Work to include terminology that was suggested by DEQ but otherwise left the work description as it was previously. This letter provides estimated costs for tasks described in the Scope of Work (a copy of the revised Scope of Work is included with this letter as Attachment A).
Table 1 lists estimated costs for performing tasks 100 (Revise Conceptual Model), 200 (Soil Vapor Extraction Pilot
Test), 300 (Optimize Landfill Gas Extraction System) and 400 (Corrective Measures Assessment). Attachment B to
this letter gives detailed unit costs and hours for each task.
Table 1
Estimated Costs for Tasks Related to Story Mill Landfill Corrective Measures Assessment
Task No. Task Description Estimated Cost
100 Prepare Updated Conceptual Model (data collection) $75,500.54
200 Soil Vapor Extraction Well Radius of Influence Test $89,189.17
300 Optimize Landfill Gas Extraction System $61,117.20
400 Corrective Measures Assessment Document $65,956.00
Total $288,762.91
As you can see, the estimated costs are substantial. As you review these costs, you should keep in mind that much
of the estimated cost for tasks 100, 200 and 300 are direct costs for drilling and installing soil vapor monitoring wells and gas extraction wells, optimizing the existing flare and gas collection system, and surveying wells,
monitoring stations, and general topography. You should also keep in mind that these tasks, though designed as basic data collection exercises, are measures that will not only support preparation of the Corrective Measures
Assessment but ultimately will become a part of the remediation system.
I would be happy to discuss these estimated costs by task with you. I will be out of the office and generally unavailable until Monday, April 28th but will be available after that. We look forward to working with you on this
project.
Sincerely,
